Lingzhe is an ancient book restorer in Xinyuan City. He is born with the ability to see spirits but deliberately keeps away from them. While repairing a diary of the Republic of China, the sealed "paper kite spirit" was accidentally released, and the truth about the "Realmation Change" recorded in the diary emerged - the covenant between humans and spirits was tampered with. Lingzhe was forced to get involved in the dispute. With the help of the Guardian Association and friendly spirits, he not only had to fight against the pursuit of the ghost hunter, but also uncovered the conspiracy behind the diary. His bloodline seemed to be mysteriously connected to the covenant a hundred years ago.
